What vehicles are most commonly affected by C0B9E?

DTC C0B9E is commonly reported in 2017-2021 Ford F-150 models, but it can also affect other vehicles with similar BCM configurations. Always check for manufacturer recalls or Technical Service Bulletins (TSBs) related to your specific make and model.

How can I prevent C0B9E from happening again?

To prevent C0B9E from recurring, ensure regular inspections of the rear camera and wiring, especially after any incidents that could cause damage. Keeping the vehicle's software updated can also help prevent glitches that trigger this code.

What is C0B9E?

The DTC code C0B9E refers to a specific issue within the vehicle's body control module (BCM) related to the rear camera system and its functionality. When this code is triggered, it usually indicates that the BCM has detected a malfunction in the rear camera circuit or a communication error with the camera module. For many vehicle owners, especially those with 2017-2021 Ford F-150s, this can manifest as a failure of the rearview camera to activate or display properly when the vehicle is in reverse gear. In some cases, the image may flicker or not appear at all on the dashboard display. This not only affects the convenience of parking and reversing but can also pose safety risks. If ignored, the issue could lead to further electrical problems or even a complete failure of the BCM, which would require more extensive repairs. It’s vital for car owners to address this code as soon as it appears to ensure the vehicle remains safe and functional.

Symptoms

Common symptoms when C0B9E is present:

  • The rearview camera does not activate when the vehicle is in reverse, leading to difficulty in parking.
  • The dashboard displays a 'Camera not available' message, indicating a potential communication failure.
  • The image from the rear camera flickers or is distorted, which can create confusion while reversing.
  • The vehicle may exhibit intermittent electrical issues, such as dashboard lights flickering or malfunctioning.
  • In some cases, the reverse lights may not illuminate when the vehicle is in reverse, compounding the visibility issue.

Possible Causes

Most common causes of C0B9E (ordered by frequency):

  1. The most common cause of DTC C0B9E is a faulty rear camera module, with a likelihood of about 60%. This can happen due to physical damage or wear over time.
  2. Another common cause is damaged wiring or connectors leading to the rear camera, which may account for 25% of cases. Corrosion or loose connections can disrupt communication.
  3. A software glitch in the vehicle’s BCM can also result in this code being triggered, especially after updates or repairs, with about 10% of instances attributed to this.
  4. Less common but serious causes include a malfunctioning body control module itself, which can lead to further electrical issues within the vehicle.
  5. Rarely, this code may be caused by a faulty vehicle speed sensor, leading to incorrect signals being sent to the BCM.
